After a week where the Storm's wrestling tactics again came under the microscope, new images emerged of Simonsson grimacing under the attention of Smith, who was penalised for the incident.

With Canberra in possession on the 30m line with just over 10 minutes remaining, Simonsson got to his feet and pushed Smith backwards before the penalty was awarded.

Smith immediately questioned the penalty as the Raiders marched down field and scored a minute later through Jordan Rapana.

Smith then raised the incident again with referee Ben Cummins.

Cameron Smith’s bemused reaction.

"I just want some clarification on what that penalty was for there?" Smith asked.

"Rubbish on the face, mate, and it was you," Cummins said.

"Rubbish on the face?" Smith said with a disbelieving laugh.

"Yeah," Cummins replied.

"Okay, no worries," Smith said.

Smith questioned Cummins twice more to which the referee replied: "Mate, I can't tell you anymore, Cameron."

"Fair dinkum. Rubbish on the face?"

The incident dragged on for the entire time Raiders captain Jarrod Croker was lining up the conversion as he reduced the Storm's lead to 18-16, before going on to record one of the great comeback victories in the club's history.

There was no shortage of spite in the game with Canberra forward Joe Tapine charged for punching Nelson Asofa-Solomona in retaliation after some push and shove in a scrum.

Smith had previously found himself at the centre of another controversy playing against the Raiders a few years back when he dropped a knee into the back of Croker's injured knee.

Storm teammate Cameron Munster was charged for a cannonball tackle on Sia Soliola on Saturday night but will escape suspension with guilty plea.

The Raiders fought back from 18-0 down, and after two players were sin binned, to defeat the runaway competition leaders on their home turf.
